Nokia Lumia 710 users can now pimp up their handset with a range of colourful The Dark Knight Rises Xpress-On covers, complete with iconic Batman symbol.

Available in black, white, blue, yellow and pink, the covers are sadly available only in the US (though eBay may be worth a visit), but our American cousins will be able to get their hands on them for free for a limited time only – namely until 31 July.

The offer is open to both new and existing customers, by either purchasing the phone in a T-Mobile store, or by visiting the Nokia’s cover giveaway page.

Batman: The Dark Knight Rises looks set to be one of the biggest blockbusters of the year, so you can’t really blame Nokia for cashing in on it. The manufacturer has already unveiled a Nokia Lumia 800 Batman edition. You can check out our pictures and hands-on account by clicking here.
